[PATCH] 9p: remove CONFIG_NET_9P_DEBUG option

[Alex Ray <alexjray.ncsu@gmail.com>]

Remove the CONFIG_NET_9P_DEBUG option, used to completely remove logging
functionality from v9fs.  Logging is (already) controlled with the
run-time debug= option, this gets rid of the compile-time option (which
was being misunderstood and misused).
